Arianna and Hannah are conducting an experiment to test the difference threshold for sense of
touch on the forehead. For trial 1. Hannah closes her eyes while Arianna gently touches 2
paperclip points 3 millimeters (mm) apart on Hannah's forehead. Then Hannah reports whether
she could feel 1 or 2 points. For each of the next trials, Arianna and Hannah repeat this process,
each time with the points 2 more mm apart. Hannah reports feeling 1 point until the points are
15 mm apart, when she begins reporting that she feels 2 points. Which inequality best
represents the trial numbers in which Hannah feels 2 points?

416.67$
Step-by-step explanation:
First, the units of the price are using square yards. To simplify early, we can convert the sides to yards.
Bedroom dimensions: 10/3 yards by 4 yards.
Since the cost is by area unit, we can find the area by multiplying the dimensions(assuming the bedroom is a square), yielding us 40/3 square yards.
Now multiplying the square yards by the price gets us:
